Project Background
My goals for this booklet...
Stone Lakes National Wildlife Refuge constructed a public-use visitor center and walking path called Blue Heron Trails in 2011. The construction of Little Green Heron Playscape, a natural playground for urban Sacramento-area children, was not completed due to unanticipated expenditures which resulted in contract renegotiation. The construction company and U.S. Fish and Wildlfie Service agreed that Little Green Heron Playscape would not be included in the new scope of project.
1. Introduce the site and proposed master plan for Blue Heron Trails 2. Expand on several proposed design features for Blue Heron Trails 3. Illustrate the design process of Little Green Heron Playscape (considered the primary feature of my senior project) 4. Present the construction underway at Little Green Heron Playscape 5. Showcase my passion and skills for landscape architecture 6. Aquire a position that works under a licensed landscape architect

Stone Lakes National Wildlife Refug Stone Lakes National Wildlife Refuge sacramento, california Sacramento, California

Refuge Mission Statement The refuge is dedicated to conserving, enhancing, restoring, and managing Central Valley wetland, riparian, grassland and other habitats to benefit native fish, wildlife, and flora. U.S. Fish and Wildlife Service manages all 6,000 acres of Stone Lakes NWR, striving firstly to restore the land that was once a flourishing stopover area for migrating shorebirds and waterfowl in fall and winter. Blue Heron Wetland and Marsh 6 (left) are boundary man-made wetlands, attracting wildlife and retaining urban stormwater.
3
What is Blue Heron Trails? Blue Heron Trails (above) is approximately 10 acres with an existing one-mile paved trail; this is the only land accessible to the public. Constructed in 2011, this public open area was constructed to fulfill the visitor services requirements for SLNWR Comprehensive Conservation Plan.

5 Proposed Wetland Model This raised boadwalk carves through the southwestern portion of Discovery Wetland. Tules, the common name for a six-foot water reed, fills this section of the wetland, creating an allee.
Proposed Circulation The paths are rectilinear, often blocking one’s view to the next turn, producing a maze-like feeling for children and adults.
Existing Discovery Wetland One could observe western pond turtles or aquatic garter snakes sunning in pockets of water amongst the dense tle cover. Environmental education explaining the benefits of wetlands, especially in regards to carbon sequestration, should be posted at on of the two boardwalk nodes.

Prior to the design of Little Green Heron Playscape, it was essential to submit design considerations for the entire visitor accessible area. The masterplan and tule maze boardwalk are spatially significant to the design to the roposed playscape. School groups regularly attend field trips at Stone Lakes NWR; the amphitheater accomodates up to 300 children.

Little Green Heron Playscape Design Concept Statement 8
Design Goals
1. Create a horticultural learning environment by establishing regionally native and community specific flora 2. Establish a sense of place by manipulating views to avoid unnatural, urban elements 3. Create a space that offers unstructured play for children with natural elements 4. Offer opportunities for wildlife observation of migratory birds in adjacent inaccessible wetlands 5. Spatially organize natural play features in the playscape to accommodate multiple age groups 6. Develop opportunities for environmental education 7. Produce a playground that avoids using prefabricated equipment and pursues natural materials with limited man-made components 8. Design in accordance to federal safety regulations in regards to public open space to support a safe environment for children to play.
Design Concept and Thesis
“Little Green Heron Playscape: a place where children play unstructured, unsigned, and where they’re not told what to do.” People are losing touch with nature due to limited access to the outdoors, the increased use of technology, and the common parental fears of unsafe adolescent environments. The widespread establishment of natural playscapes can reengage children, parents, and the public with their natural world by providing unstructured, outdoor recreation.

Playscape Master Plan Little Green Heron Playscape Understanding the design It’s okay to play. Little Green Heron Playscape is a place where children can play unstructured in a natural environment. Retaining the existing location of the playscape, screening the urban environment from visitors, introducing shade, and preserving the existing vegetation were the main factors that produced the design. The spatial arrangement of the many small-scale spaces is optimal for circulation, vantage points, safety, plant species health, and asthenics. A wildlife observation deck is situated atop a manmade hill in order to view nearby wetlands, which are impossible to view with the existing flat terrain. The topography of the playscape is intricate and complex: a concept that can evoke the sensation of viewing an “untouched landscape.” This plan is not labeled like the original, however, many features of Little Green Heron Playscape are distinguishable. For example, the spiraling brown form composed of circles are vertical logs implanted into a grassy knoll. This play feature is an abstraction of hopscotch. Return to these pages to find the location of features described later in the booklet.

It is a goal to increase opportunities for wildlife observation in adjacent wetlands and marshes. In order to accomplish this goal I increased the elevation of the southwestern portion of the playscape. This large landform is cut soil from future wetland construction nearby. It allow adults and children a rare opportunity for wildlife observation in an urban setting. The platform can educate about sandhill cranes and the protection of migratory birds. The landform is also a play features for children to run up and down or play king of the hill or slide down the subterranean slide. The slope necessary for specific plants in the pollinator garden and forb hillside along the ramp. Moreover, the observation platform serves as a shaded, elevated vantage point where adults can monitor their children.

Sandhill Observation Deck
wildlife observation 21 Stone Lakes National Wildlife Refuge is an important stopover area for migrating shorebirds in the fall and habitat for wintering waterfowl like Sandhill Cranes, Snow Geese, Canada Geese, and many duck species. Sandhill Observation Deck gives visitors an opportunity to have a unique vantage point to watch the migratory birds set down into nearby Blue Heron Wetland and Marsh 6 each fall and winter. The raised deck has a wooden seat wall that wraps around a valley oak tree, which offers shade. The overhead structure likewise offers shade. An educational panel on sandhill cranes also blocks the direct view of a transmission tower. The steep grassy grade encourages children to race to the top of the hill, play tag, king of the hill, and slide belly down the tunnel log. Grass stains are encouraged!
Hand Perspectives Little Green Heron Playscape Sculptural Entry Archway
22
The entry arch is an iconic threshold that children and adults cannot forget. The vertical wooden posts are rough cottonwood trunks and the large beam is an oak trunk salvaged from an underwater site in Stone Lakes NWR. The crossroad direction sign points to other Refuges near and far. The cranes, otters, beavers, and dam are brass sculptures.
Hand Perspectives Croaking Frog Creek
This man-made creek winds through the playscape and into Discovery Wetland. A suction pump is located beneath the entry deck of the playscape. The creek outflow is covered by a large boulder climbing element to encourage play and prevent tampering.

Nature Art
Willow Nest
Children are intrigued with play features that are scaled to their body size. The space designated for nature are in the playscape is envisioned to be “continuously temporary.” As the playground matures, a new nature art feature could be installed. This sketch illustrates “oak tree trunk frames,” which is a play feature that frames children’s faces. Weaving supple willow branches, which can also be found on the refuge, can create similar forms for children to interact with. This space is created to hold temporary natural sculptures.
A mother watches her son balance across a log over Croaking Frog Creek to his sister in the willow nest. This design feature is an abstraction of a red-winged blackbird nest, which situates its nest near a water source, secluded from traffic within the bulrush reeds. The nest is surrounded by a swale from which bulrush grow, representing a similar environment. The nest is constructed by weaving supple willow branches around a donut-shaped form. The feature is depressed into the grade to discourage pests.

Playscape Construction Stone Lakes NWR Summer 2014 26
During the last two weeks of my employment with US Fish and Wildlife Service, a public organization dedicated $5000 to contribute towards materials for Little Green Heron Playscape. It was my responsibility to use the allocation, which had to be emptied in 10 days. I purchased boulders for the natural climbing space, Netafim irrigation for the grass berms, and decomposed granite for the proposed pathways. USFWS decided to transfer my last 80 hours of work towards constructing the playscape. This is what I accomplished

After five years I graduated under a department that Design Intelligence ranked the fourth best landscape architecture and design school in the U.S. During the summers, I worked in Sacramento and Elk Grove for Stone Lakes National Wildlife Refuge specializing in irrigation implementation, conservation practices, project management, general maitenance, and practical design solutions.
Some remark that landscape architecture is a profession on its deathbed in this postmodern society. I disagree: landscape architecture is the savior of our sprawling urban environment. It produces connections to public policy, cultural and social progression. Successful design must create a sense of place, nostalgia, and meaning. I am passionate about designing contextually to the site, users’ needs, native flora, and materials. During the design process, I strive to never neglect the unique function, audience, flora, and materials of a place. The professional experience I have accumulated influences me to design with a pragmatisim that favors the reduction of maitenance and durability.
